Ergonomics
Ergonomics is the scientific discipline concerned with the understanding of interactions among humans and other elements of a system, and the profession that applies theory, principles, data, and methods to design in order to optimize human well-being and overall system performance. It involves the application of Psychology, Physiology, and Engineering principles to design and improve products, systems, and environments. The goal of ergonomics is to reduce Suffering and improve Livability by designing systems that are compatible with the needs, abilities, and limitations of people. This field is closely related to Walkability and Building block concepts in urban planning. Ergonomics also draws on Theory and Causal relationships to understand how humans interact with their environment.
